IMPROVED METHOD 0F CHARGING WATERVWIIH CARBONIO ACID.

Speciiication forming part of Letters Patent No. 55,0110, dated May 29, 1866.

To all whom fit may concern:

Be it known that I, J AMEs S. BALDWIN, ot' the city, county, and the State of New York, have invented or discovered a method of preparing and charging vessels with carbonio acid in water or any other liquid in which the said carbonic acid will dissolve; and Iinclose in a close vessel, A, the water or other liquid to be charged and a sufficient quantity of previously=prepared solid carbonio acid in charger B, which byits volatilization produces the necessary pressure to produce or give the solution ofthe gas so formed. In some cases I prefer to inclose the solid carbonio acid in a separate vessel, 0, and allow the gas formed by its v olatilization to pass through a tube, D, or other passage into the waterl or liquid to be charged; and I hereby declare that the the following is a full andsufticient description thereof, reference being had to the ac-v companyin g drawings and references markedthereon.

In the drawing hereof, letA represent the vessel containing the liquid to be charged, and let B represent the receptacle ofthe solid carbonic a;c id, so perforated as to allow the gas resulting from the volatilization aforesaid to pass into the Water or other liquid and be dissolved therein. The use of this receptacle B is not indispensable, but is convenient, and the acid could be introduced therein without any cover or protection.

C represents aseparate vessel,whicl1 may be substituted for the vessel B, containing the carbonio acid, and connected to the aforesaid vessel A by means of the tube D D, through which thesolid carbonio acid charged into the said vessel C passes, in consequence otl its volatilization 'in vessel C, and becomes absorbed into the liquid contained in the aforesaid vessel A. rlhe said volatilized carbonio acid also passes through the screw-cock E before it enters the liquid to be charged. The aforesaid screw-cock E is also used for the purpose of closing up the said vessel A, when it is to be preserved for future use or for transportation from place to place. rIhese two charging-vessels B or G may each be used for the same purposeviz.,for charging the reser- Voir A-and they are regarded each as the equivalent of the other.

In the apparatus above described the use of pumps and other machinery for forcing carbonic acid into the reservoir A is entirely dispensed with.

In the preparation of the fountain or vessel A for receiving` the carbonio acid in the gaseous state,- the usual quantity of water is first poured into the fountain, as is done in thechargin g of soda-fountains by the ordinary means.

Myinvention does not relate to the discovery of solidifying carbonio acid, but to the application of the solidified acid to apractical` purpose in the domestic arts. Although this solidiiication was discovered some forty years ago, no practical use ofthe scientific fact has been made up tothe present day.

I propose, therefore, to introduce this compound to subserve a great and valuable purposeby showing that it may be used for charging reservoirs so cheaply that it may be sold and delivered to our houses as readily asice is now distributed to *theIl domestic household. It is only necessary to show that the acid may be obtained by utilizing the waste products ot'manufactures of the cheapest kind and at asmall cost-even less than that of any other known preparation., It is believed that the introduction and use of cheapened processes for obtaining soda-Water and rendering this drink universal would do ver much to diminish the use of wines and intoxicating liquors. It' I have been the first to utilize this product-solid carbonio acid-and adaptit to Charging water or other equivalent liquid with carbonio acid by inclosing said liquid, with solid earbonic.acid,in the same vessel or series of vessels, substantially inthe manner and for the purpose herein set forth.
